6.2 SAFETY DEVICES
DHOLLANDIA hydraulic ramps are equipped with multiple safety devices in order to ensure that goods can be loaded and unloaded
with maximum safety for the operator, any incidental bystanders, and the load itself. The following safety devices are incorporated or
recommended on most hydraulic ramps:
Electrical safety valves mounted on all cylinders [standard]. The safety
valves lock the oil inside the hydraulic cylinders as long as they are not
energized via the electrical controls. The purpose is to secure the platform
in its travel position while driving, or in any other fixed position, in case of
accidental failure of a hydraulic pipe (as soon as the electrical controls are
released).
DHOLLANDIA safety valves are equipped with a manual emergency control,
allowing the operator or repair agent to open the valve manually in case of
electrical failure (see MAINTENANCE AND REPAIR MANUAL).
Platform fold lock [optional]. The foldable point of foldable ramps DH-AR2*
can partially swing open and shut when driving on uneven roads.
DHOLLANDIA strongly recommends such kind of lock to:
reduce driving noise
reduce the wear of the articulation pins and bearings in the articulation
between the 2 platform sections.
The foldable point of foldable ramps DH-AR3* / AR4* should be pressurized
by means of the control box when closing it up in travel position. It is still
good practice to add a locking device, to prevent a platform fall in case of
accidental loss of hydraulic pressure.
NOTICE
In order to maximize the longevity of articulation pins and bearings, it is important that the platform is pressurized and firmly
secured in its travel position.
In case of full height bodies: if the platform can be closed and pressurized against the rear frame of the body, no further
measures besides a platform fold lock are required.
In case of flat-bed or drop-side bodies: fixed or demountable stanchions MUST be foreseen at the rear of the vehicle floor,
against which the platform can be pressurized. DHOLLANDIA strongly recommends to use chain binders, ratchet straps or
similar solutions to pull the rearmost platform section against the stanchions, and pressurize the platform in a safe travel
position in this way. Examples:

15
DHOLLANDIA
Pressure relief valve [standard]. Safety device integrated into the pump unit, protecting the hydraulic circuit and components
against excessive pressure while CLOSING the platform.
Pressure compensating flow valves [standard]. Flow valves are integrated
in the hydraulic circuits to ensure the platform opens at a safe speed under
all foreseeable circumstances of normal use.
Hydraulic stabilising legs [optional]. Stabilising legs can be mounted at the
vehicle chassis or body, to support the chassis of the vehicle and protect the
platform of the ramp while loading and unloading. [see also section 9.7 from
page 41 onwards].
The use of stabilising legs is mandatory on certain vehicles, Consult the
Fitting and Body Building Instructions of the vehicle manufacturer and make
sure you comply.
Mechanical support legs [standard]. On foldable platforms, mechanical legs
are used to support the articulation between the 2 platform halves, when the
platform is rested at the ground. They MUST be set in firm contact with solid
ground before loading the platform.
Overload relief system [standard]. The platform should only be loaded when
the outboard platform edge and the mechanical support legs (if applicable)
are in firm contact with the ground.
This system automatically opens the safety valves on the hydraulic cylinders
and drops the platform down to the ground if it is loaded without being fully
deployed as described above.
2-hand external control box [standard]. On the external control box
mounted in fixed position at the side of the vehicle body, all functions are
actuated by means of a control switch and a safety switch. The compulsory
use of 2 hands to actuate the various lift functions, protects the operator from
crushing his / her head, limbs or upper body between the CLOSING platform
and the rear frame of the vehicle body.
Hydraulic ramp on/off switch [min. 1 compulsory]. Depending on
configuration, the electrical power to the hydraulic ramp is switched on / off
by means of:
1. A cabin switch (provided by the truck manufacturer or DHOLLANDIA
[option OAE503.1]). This switch enables the operator to switch the
control power to the main external control box on / off.

16
DHOLLANDIA
2. A main battery disconnect switch integrated in the external control
box [optional]. This switch enables the operator to switch the main
battery power to the hydraulic ramp on / off. If available, the operator
MUST switch off the main battery disconnect switch after each use of
the hydraulic ramp.
3. A combination of both
Fuses [standard]. A 15A fuse for the electrical control circuit comes mounted in the pump unit and in the main external control
box (for most types). A 150 –250A fuse for the electrical main battery circuit is supplied by the truck manufacturer or by
DHOLLANDIA. Both fuses protect the electrical circuits against short-circuits and amperage peaks.
Decals [standard]. The hydraulic ramps are supplied with a number of
operation deals, load diagrams and safety decals, most of them to be
applied to the vehicle body during installation. These decals must
always be kept clean and legible and replaced whenever required.

the limits of the applicable load chart, and in compliance with the operator instructions and safety instructions in this manual.
The operator should follow all other policies and procedures applicable to the job situation including health & safety regulations,
road and traffic regulations, as well as company procedures. The operator should not use the hydraulic ramp if he/she cannot use
it in accordance with all applicable regulations and instructions.
The operator must be at least 18 years of age.
7.2 GENERAL SAFETY INSTRUCTIONS
WARNING
To avoid serious bodily injury or death, the operator must use appropriate work clothes. NEVER wear loose-fitting clothes that
may be trapped in the moving parts of the hydraulic ramp. ALWAYS wear professional safety-toe shoes, protective gloves,
and eye protection. Use of hardhat is recommended.
Slipping (and falling) can result in serious bodily injury and death. To prevent injury by slipping:
oALWAYS wear professional safety-toe shoes with a good non-slip sole.
oDO NOT use the hydraulic ramp if it is covered with snow, mud, dirt, debris, liquids or other substances.
oDO NOT run on or off the platform.
Tripping (and falling) can result in serious bodily injury and death. To prevent injury by tripping:
oNEVER leave the hydraulic ramp unattended in partially open position.
oPay attention to protruding items on the platform surface at all times (ex. platform lights, wheel blocks,
other foreign objects, etc.).
oDO NOT run on or off the platform.
Falling from the platform can result in serious bodily injury and death. To prevent injury by falling:
oMake sure your footing is solid. DO NOT run on or off the platform.
oNEVER move the vehicle while a person is standing on the platform or inside the vehicle body.
oNEVER use the platform as an elevated working platform.
WARNING
Improper use of the hydraulic ramp will put the operator and other parties at great risk of serious bodily injury and death.
To reduce the risk of serious bodily injury to the operator and any bystanders, the use of the hydraulic ramp is restricted to
skilled operators, who have been properly trained, and who know and understand the full contents of this manual.
To reduce the risk of serious bodily injury or death, THE OPERATOR MUST COMPLY WITH ALL SAFETY INSTRUCTIONS
AND WARNING LABELS IN THIS SECTION AND THE ENTIRE MANUAL before and while operating the hydraulic ramp.

18
DHOLLANDIA
WARNING
Prior to operating the hydraulic ramp, the vehicle must be safely parked on level and solid ground, the parking brake applied,
and the engine must be switched off. Lock open the rear doors and secure all other moving parts of the vehicle body. Failure
to abide by these instructions can result in serious bodily injury or death to the operator or bystanders.
Prior to releasing the mechanical platform lock (if so equipped) and using the hydraulic ramp, check if the hydraulic ramp can
be used safely. Take precautions to ensure your own safety, and the safety of bystanders or other parties in traffic. Clear the
working area of any objects that could potentially impede movement of the hydraulic ramp. Failure to abide by these instructions
can result in serious bodily injury or death to the operator or bystanders.
Ensure that the vehicle cannot become unstable when
putting heavy weight on the platform. If the vehicle or the
hydraulic ramp are equipped with hydraulic stabilising legs,
deploy these before opening the platform. Ensure that the
stabilising legs are positioned on solid even ground.
In case of soft terrain (sand, gravel,…), solid support blocks
MUST be used under the stabilising legs. Failure to abide
by these instructions can result in serious bodily injury or
death to the operator or bystanders. Lock the air suspension
of the vehicle, so that the vehicle floor cannot rise after
deployment of the stabilising legs.
If the vehicle or hydraulic ramp are not equipped with
stabilising legs, and if the operating instructions of the
vehicle manufacturer allow so, lower the vehicle air
suspension, and lock it in this position.
The purpose of this is to ALWAYS keep the floor height of
the vehicle unchanged while loading / unloading, prevent
potential overloading and material damage to the hydraulic
ramp or vehicle chassis.
ALWAYS make sure that the outboard platform edge and the mechanical support legs under the platform fully rest on solid
even ground before loading the platform. In case of soft terrain [sand, gravel, etc.) ALSWAYS use solid support blocks to
support and stabilise.

19
DHOLLANDIA
WARNING
ALWAYS make sure you have sufficient free space to load / unload and maneuver the load safely. ALWAYS make sure a
safety distance X. is kept between the back of the vehicle and the following vehicle or nearest obstacle.
To reduce the risk of serious bodily injury or death of the operator
and third parties in traffic, ALWAYS make sure the platform is
clearly visible to other persons from all approach directions.
DHOLLANDIA recommends the use of 4 warning cones, placed
around the work area of the platform.
When the hydraulic ramp is operated near vehicular traffic, wear
working clothes in high-visibility colors and a high-visibility safety
vest.
To reduce the risk of serious bodily injury or death, make sure the
working zone is sufficiently lighted.
Inspect the hydraulic ramp prior to each use. If any unsafe condition exists or unusual noises or movements are noticed, DO
NOT use the hydraulic ramp and contact an authorized DHOLLANDIA service agent for repair. Please see ‘pre-trip inspection’
procedures from 7.5 page 24 onwards.
Read and comply with all warning decals, pictograms and instructions affixed to the hydraulic ramp. Failure to abide by warnings
and instructions may result in serious bodily injury or death.
The hydraulic ramp must not be used if the operator is intoxicated, impaired or distracted in any way. NEVER use a phone or
mobile device when operating the hydraulic ramp.
The hydraulic ramp shall be used by means of original control units only. Operating the hydraulic ramp with unauthorized control
units will increase risk of serious bodily injury or death to the operator or any bystanders.
Limit the operation of the hydraulic ramp to one single operator. Operation of the hydraulic ramp by more than one operator at
a time may cause confusion and increase the risk of serious bodily injury or death.
